In this article we will demonstrate three ways of deployment and undeployment on Weblogic Server 1. Using WLST 2. Using JMX 3. Using build script. Application Deployment using WLST connect(‘weblogic’,’weblogic’,’t3://localhost:7001′) edit() startEdit() deploy(‘CookieApp’,’D:/Replications/CookieApp’,targets=’AdminServer’) save() activate() exit() Application Undeployment using WLST
